Composting dry poultry excrement, broiler manure or separated pig slurry fully automatically is now possible: with the CompoLiner from Big Dutchman.

After developing and testing the innovation for several years CompoLiner is now ready for serial production and released for sale worldwide. The composting system is easy to operate, has a fully automatic process control and can easily be adjusted to handle the amount to be composted. Big Dutchman product engineers have put many hours of work into the system, and their work has clearly paid off.

Inside the ready-to-be-connected composting system, microorganisms degrade the organic input material, e.g. dry poultry excrement, broiler manure or separated pig slurry, in an aerobic environment. The resulting, very valuable organic fertiliser can be used for general soil improvement in horticulture and agriculture.

Flexible composting system: CompoLiner consists of at least two and no more than eight 40” containers (80 to 360 m³)

An automatic conveying system or a wheel loader transport the input material, which should have a dry matter content of more than 40 percent, to the filling side, where it enters CompoLiner. A lane turner then ensures that the material is milled, homogenised and conveyed to the discharging auger. The lane turner can move freely along the entire system length. A specially developed aerated floor is responsible for the directed supply of oxygen. A compressor continuously guides the fresh air and thus the oxygen required for degradation into the material. Temperature and oxygen content in the compost are permanently measured by a sensor. The composting process therefore automatically takes place under ideal oxygen and temperature conditions. After a specific storage period that depends on the composted material, an auger discharges the compost at the other end of the container.

Advantages of CompoLiner

  • Modular setup consisting of 40-foot (standard) containers
  • Therefore a variable capacity from 80 to 360 m³, which corresponds to approx. 50,000 to 200,000 layers
  • An integrated control unit in a cabinet in the rear end set controls the system
  • Good resistance to corrosion since the entire system’s interior is lined with stainless steel
  • Central emission extraction
